The patch adds the test framework for OVS using afxdp. Currently there are two test cases, using ping and http as traffic forwarding through ovs with 2 afxdp netdev. Signed-off-by: William Tu <u901206

The patch creates a new netdev type "afxdp" and copies some of the afxdp api implementation from xdpsock_user.c at linux sample code. The afxdp ebpf programs/maps are loaded when dpif-netdev is create
